We're sure almost everyone has heard the song Mick Konstantin wrote about Conor McGregor.
The tune went viral on Facebook this week, and was even shared by the man himself.
However, Conor has now revealed that he reached out to Mick - and is flying him and a friend over for his fight with Floyd Mayweather in Las Vegas later this month.
"It was one hell of a song, it’s a very catchy song. We actually reached out to the guy," Conor said in an interview with the MMAFighting YouTube channel.
"I had my people reach out to the guy and we’re booking him a flight, him plus one. I’m going to bring him over to the fight and get him tickets and put him up in a hotel, and I’ll meet him after the fight. It’s one hell of a song."
Conor didn't confirm whether Mick was going to play him out to the ring, but said, "I’m going to bring him in as a thank you for the support. What a song, it’s the journey in music form. Myself and my team, we enjoyed it very much, and we’re going to fly the guy out. Him and a friend."
Speaking about Conor's kind gesture, Mick said, "Just the craziest thing of all time! Flights, accommodation and tickets sorted by the main man. Cannot even begin to thank himself and all his crew enough!
"They really are legends, and will never ever forget this gesture! Really is the stuff of dreams! Going to take a while for this to sink," he said.
